To all whom imag/concern.'

Beit' known that I, JosErH GAYNOR, a

citizen of :the United States, residing at New York city, county andState of New York, have invented new and useful Improvements inResilient Tires, of which lthe following is a specication.

This invention relates to a resilient tire of novel construction, whichis durable, pos-- sesses an effective spring action and may be readilyfitted to a wheel of conventional construction.

In the accompanying drawing: Figure 1 is a cross section ofa tireembodying my invention, on line 1, 1, Fig. 2. Fig. -2 is a longitudinalsection partly in side view of part of the tire, and Fig. 3 a crosssection on line 3 3, Fig. 2.

The wheel rim is composed of a pair of flanged rings 10, adapted tostraddle opposite sides of the felly 11. Rings 10, are provided with anumber of radially extending apertu'red lugs 12, the lugs of one ringbeing tapped for the reception of screw bolts 13, by means of which therings may be tightly drawn. together, so as to become firmly seated uponthe wheel. In addition to lugs 12, rings 10 are provided with aperturedlugs 14, that constitute bearings for the gudgeons 15 of oscillativeplate 16 having central openings 17 into which are tapped the lcwerthreaded ends of cylinders 18. These cylinders have flanged outer ends19 and are adapted to receive hollow cup-shaped plungers 20, havingcorrespondingly flanged inner ends 21.

. The several plungers 2O are encompassed by, and are secured to, acommon resilient steel band 22, arranged concentrically to felly 11.,and made of a strength that corresponds to the load to be carried bylthe tire. Band 22 is provided along its edges with radially slittedoutwardly extending flanges 23. Between the latter is confined aplurality of metal strips 24 that are loosely placed upon band 22 in atransverse direc? tion, said strips being held in position by an outerendless binder 25 stretched tightly around the strips. Binder 25 is inturn encircled by a rubber or other resilient shoe 26 which is also heldin position 'by flanges 23. Those strips 24 that are located oppositethe plungers 20, are each provided with an inwardly extending screwboltv27 that ,passes through la corresponding aperture of band 22 and ofthe plunger head. The

strips 24 serve to reinforce bandi22, and also 'to lcarry the bolts 27,so that the band is not by them unduly strained. Bolt27 carries a nut 28within the plunger by means of which the plunger is securely attached tothe band.

Between the band and the plunger there is A interposed a pillow 29,which is dished to conform tothe bulgedshape of the plunger, andconstitutes a bearing for the same. At the sides, the tire is closed 'bymeans of a pair of convex annular plates or cheeks 30,

- which are at their inner ends fastened to the rings 10, while theirouter yends slidably overlie the flanges 23. In addition tothe cheeks30, the tire is provided with a pair of canvas or similar foldablesheets 31 attached to and Vstretched between the rings l() and band 22.A number ofv holsters 32 mounted upon the ringsl, limit the inward.,y

displacement of the "band 22 andV consequentlypof the shoe 26 under loadpressure.

It will be seen that my., improved tire lacks any springs or othercushioning members excepting the resilient band 22, the parts 16, 18, 20merely serving for yieldingly holding the band and shoe tothe wheel 'rimand for transmitting the propel-- ling power from the rim to said shoe.That portion of the shoe which is intemporary contact with the road bedbecomes flattened to an extent which depends upon the load while theremainder of the tire is correspondingly expan ded,both of thesedeformations taking place against the inherent resiliency of band 22.The fiattening of the latter will cause plungers 20 to be moved inwardwithin cylinders 18, while the remaining expanded band section, willbecome raised into a position slightly eccentric to the wheel rim, whichrelative movement between tire and band is rendered possible by thepivotal connection between plates 16 and rings 10.
